  • This twelfth embodiment is constructed by attaching a brake mechanism 98 to the connector receptacle 61.
  • a brake body 99 comprises an arcuate shoe 100 bent in conformity to the curvature of the outer periphery of the connector receptacle 61 and a plate-shaped follower 101 integrally formed with the arcuate shoe 100. That side of the arcuate shoe 100 which contacts the outer peripheral wall of the connector receptacle 61 is fitted with a pad 102 prepared from elastic material such as rubber.
  • Tension springs 103 are stretched between the inner wall of the light source device body 6 and plate-shaped follower 101 to urge the brake body 99 away from the connector receptacle 61.
  • a cam 105 rotated by a knob 104 penetrating the front panel 18 of the light source device body 6.
  • the brake body 99 In a first position, as indicated in FIG. 17, the brake body 99 remains lifted by the tension springs 103, rendering the connector receptacle 61 freely rotatable. Where, however, the knob 104 is rotated about 90° in the direction of an indicated arrow A, the brake body 99 is pushed downward by the cam 105, causing the shoe 100 to be pressed against the connector receptacle 61 with the pad 102 interposed therebetween, thereby keeping the connector receptacle 61 unrotatable. When, therefore, connected to the connector 5, the connector receptacle 61 is prevented from being unexpectedly rotated.
  • This thirteenth embodiment is constructed by fitting the connector receptacle 61 with a mechanism 106 for displaying a number of rotation of the connector receptacle 61.
  • the outer peripheral wall of the connector receptacle 61 is fitted with a surrounding gear 107, which is engaged with a larger gear 108.
  • a pointer 110 is fitted to the central shaft 109 of the larger gear 108.
  • the pointer 110 is on a rotation number display graduated disc 111 mounted on, for example, the front panel 18 of the light source device body 6. The rotation of the connector receptacle 61 is transmitted to the pointer 110 through the larger gear 108.
  • the angle through which the pointer 110 is rotated displays a number of rotations of the connector receptacle 61, enabling the operator to recognize a number of rotation of the connector receptacle 61 from an indication on the graduated disc 111.
  • the connector 5 can be connected to the connector receptacle 61, after the connector receptacle 61 is returned to the central position.
